The promo has been running since 1987, and has really taken off since. Now, hundreds of game pieces are produced annually, along with all those prizes, which range from instant win food items to the $1,000,000 jackpot.

Did McDonald's and Hasbro ever think it'd grow to be such a massive phenomenon? Who knows, but they've managed to strike marketing gold.

How'd it become so successful? The game is built to get you to come back into the store. It provides enough instant prizes to give you the feeling that you're winning, but in the end, everyone dreams about scoring that Boardwalk, so they go back for more.
